The present invention relates to a method and apparatus for drying particulate materials such as seeds and grains in which an air dryer (10) having at least one drying stage containing mesh openings (20) in its bottom (16), which is accompanied by means to create an upward vertical air flow having a velocity in the mesh openings (20) at least equal or larger than to the suspension speed of the particles to be dried so that they are temporarily suspended until enough accumulate to provide sufficient weight or downward pressure for the particles to overcome the upward air flow, pass downward through one or more mesh screens (20) and reach the bottom of the dryer (10). |
